Built in the mid-17th century, likely by a local landowner or gentry family, Neillstown Castle is remembered primarily for its appearance on the Down Survey map (1655-56), an important historical record of land ownership and settlement in Ireland during the Cromwellian period. Its location near the Grand Canal highlights its potential role in regional land use and transportation developments.
